🔮

Make a hypothesis first

Predict: which design will hold the most weight?

Steps

Step 1 — Read

Read the explanation above and note the two key terms before you start.

Step 2 — Do

Step 3 — Observe

Record what actually happened, including anything that did not match what you expected.

Step 4 — Record
